Well, for one I would think that this is taking what is said to the extreame in a very obvious mistaken way. that is You have implied here that it was said that the hemispheres of the brain have been implied to work 100% heterogenous. Which of course is absurd. However, what has been shown by studies is that the two regions have statistically significantly differing function in the norm, and that the brain utilizes a "use it or lose it" scheme. So if you excercise one part the other will not develop quite so well. It is best practice, from what I have read, to make sure to excercise both hemispheres as equally as possible, training both Emotional-Intuitive(right brain), and Logical-Mathematical(left brain).

Now it is true, and dually noted that no person, with exception of those who have had a hemisphere removed, that people use both halves. However research shows that people tend towards one halve or the other. Though this is ofcourse complicated by the various tendencies of ambi-brain thinking. In which one will either use both portions simultaniously (women are more prone to this), or whole switch (men are more prone to this). As well as a large number of exceptions which make the whole discussion of Right Brain, Left Brain, more dynamic and therefore more difficult.
